Coordination in natural language hamlmrs ef tieient parsing, especially due to the multiple and mostly unintended candidate conjuncts/disjmmts in a given sentence that shows structural aml)iguity. The l)rol)lem gets more serious in a coml)inatory categorial grammar framework, which is well known [or its coral)etent treatment; of coordination, as tlm tlexil)ility of syntactic analysis ofl;en strikes back as Sl)Urious amt)iguity. We t)rot)ose to address these ambiguities with predicate argument structures and semantic ('o-occurrence similarity intbrmation, and present encouraging results.
